How long do CFL lights last?
CFL lights last approximately 10,000 hours. This assumes, however, that once the light is turned on that it will stay on for about 3 hours. Turning the lights on and off frequently reduces the lifespan of the bulb.
How much energy does an LED bulb use?
CFLs use around ¼ of the amount of energy that an incandescent bulb does, making it an energy-efficient choice. LED lights use only 3% of the energy of an incandescent bulb, which lowers your energy bills even more.
What is an LED light?
LED lights are considered a solid state lighting bulb (SSL). This means that instead of generating light and heat through something, they produce light through diodes or semiconductors. These conductors are known as a p-n junction 1, where positively and negatively charged ions meet. They force the electricity to run in a particular direction, which produces light. If the wrong type of voltage is supplied, you may hear a buzzing sound when using a dimmer meant for incandescent bulbs. Therefore, if you are switching to LED bulbs, you may need to replace your dimmer switches.
How much does a CFL bulb cost?
Costs. CFL bulbs cost around $22 for a pack of six bulbs, while LED bulbs cost around $30 for the same number. If you choose to install a new fixture that will match either of these bulbs, the cost is usually around $10 to $20 for recessed light 2 cans, which is the most common type of fixture installed today.
Why are LED lights not used in table lamps?
They are not always suitable for table lamps because they do not cast consistent light. For these purposes, invest in what is known as symmetrical LED lights, which are LEDs that have a diffuser to cast the light evenly around the room. These lights often have LED clusters inside that produce light in a variety of directions, making them easier to use anywhere. Always check the label to determine which type you are purchasing.
